maradnak. Az állategészségügyi igazgatás arra törekszik, hogy egyelőre az enzootiásnak ismert területen a házilag levágott sertések húsát is megvizsgálják, ezért az elmúlt években 340 mikroszkópot bocsátott e célra a gyakorló állatorvosok rendelkezésére. A szerző végezetül a trichinellosis elleni védekezés egyéb rendszabályait ismerteti, amelyek a sertésnek a vadon élő emlősöktől való fertőződését vannak hivatva megelőzni. NEMESÉRI, L.; Trichinellosis in Hungary The author discusses trichinellosis in Hungary. During the 54 epidemic cases observed since 1891, 536 individuals have been infected, and 18 (3,3 per cent) died of trichinellosis. The severest epizootic (1964) is treated in detail. Of the 1141 diaphragms taken from human corpses and examined by several workers 18 (1,5 per cent) proved to have minor infections. Information on the trichinellous infection of the pig has beeravailable since 1891: since then Trichinella larvae have been repeatedly demonstrated both in animals slaughtered at home and formerly in those exported. According to statistics, the trichinellous infection of the Hungarian pig stock is low. The natural hosts and vectors of the Trichinellae are wild mammalian species, primarily the fox. This is the case in Hungary also. Generally 5 per cent of foxes have trichinellous infection, and 0,5 per cent of wild boars. Two per cent of dogs and cats in the enzootic area of Comitat Haj du-Bihar were infected. The source of human infection is, in most cases, sausages

•prepared from the meat of pigs slaughtered on the farm ~,nd only rarely from wild boars shot in the country. Infection of pigs occurs mainly by their devouring the carrion of wild mammals, particularly that of the fox. Since 1962, inspection for trichinellosis of pork slaughtered for public consumption or export, has been obligatory: 130
